Fiber would be serious competition for AT&T if it ever rolls out because Alphabet (NASDAQ: GOOG) wants to bring the service to some of the cities where AT&T offers U-verse. A list of cities for possible Fiber rollout includes Raleigh, Charlotte, Chicago and Los Angeles, all areas were U-verse is available. Fiber already competes directly against U-verse in Austin and Kansas City, and it will be rolled out in San Francisco and San Antonio, where AT&T operates.
